Let the hive mind of Engadget get that for you.
"I'm looking for a wireless trackpad to use with my older (2.5 or so years old) C2D MacBook that's perpetually docked to my home theater. Something sleek, thin, not too small, made of high quality materials. Ideally, it would natively support all of (Snow) Leopard's multitouch inputs, and even more ideally, it would have a charging dock / base. The only problem is that I'm not sure that such a thing even exists. Think you can throw me a bone?"
Anyway, responding to the previous poster, Nintendo wasn't actually the first to lock out third parties from their consoles. Atari was. The Atari 7800 encryption was years ahead of its time and was never broken, though I think someone was eventually persuaded to leak the signing key a few years back. Nintendo only followed suit when they brought the Famicom to the US; the original Famicom had no lockout chip.
